RING-RAIL MOTION FORSPlNNlNG-MACHINES.

SPECIFICATION forming part of Letters Patent N0. 749,521, dated January 12, 1904.

Application filed August 12, 1903. Serial No. 169,268. (No model.) i

To all whom it may concern:

Be it known that I, MANTON T. BENTLEY, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Ring- Rail Motions for Spinning-Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to ring-rail motions for ring-spinning machines.

In the spinning and twisting of threads or yarns of different descriptions on so-called ring-spinning machines the uniform movement of the rails which carry the rings and travelers (called ring-rails) back and forth along the length of the spools or bobbins is necessary in order to obtain the proper distribution of threads on said spools or bobbins.

The object of this invention is to provide a simple and smooth working mechanism for the above purpose, so that by dividing each ring-rail into a plurality of sections said sections may be simultaneously moved upward and downward, one section serving to' counterbalance another section, and thereby reducing to a minimum the strain, tension, or fricparts shown in Fig. 1.

tion on the mechanism from which the ring rail derives its motion.

With the above and other objects in view, the nature of which'will more fully appear as the description proceeds, the inventionconsists in the novel construction, combination, and arrangement of parts, as hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a front elevation of a sufiicient portion of a ring-spinning machine to illustrate the construction and operation of the present invention. Fig. 2 is a detail elevation showing the balance-weight which serves to maintain the operative relation between the parts of the mechanism by which motion is transmitted to the ring-rail. Fig. 3 is a plan View of the Fig. 4 is a vertical cross-section taken a little to one, side of the center of the machine.

Like reference-numerals designate corresponding parts in all figures of the drawings.

In carrying out the present invention the ring-rail at each side of the machine is divided into a plurality of sections 1 and 2. For the purposes of illustration and disclosureof this invention said ring-rail is illustrated and will be described as composed of two sections, although itwill be apparent that the sections may be increased to any desired extent in accordance with the size and capacity of the machine.

- Each ring-rail section is carried by and mounted upon the upper ends of a plurality of vertical lift-rods'3, 'two of said rods being shown for each ring-rail section. The liftrods 3 play vertically in guides 4, secured to one of the stationary rails f the machineframe, each guide by preference consisting of an upperring or sleeve 6, a lower ring or sleeve 7, and a connecting-bar interposed be tween and rigidly connecting said rings, whereby two distantly-located bearing-points 'are provided with each lift-rod 3, thus causing the same to work steadily in its movements up and down.

' Each lift-rod 3 is'provided at its lower end with a foot-piece 8, which is internally threaded and screwedupon the threaded lower end of said rod, as shown, and held when adjusted by means of a jam-nut 9, thus providing for increasing or diminishing the distance between the ring-rail section and the lever which cooperates with the lift-rod. In this way the ring-rail section may be leveled up and the extent of motion up and down regulated to, suit the spool or bobbin upon which the thread or yarn is being wound.

10 designates a rock-shaft, which extends transversely across the machine and has rigidly monnted thereon a single-arm lift-lever '11, which'carries at its end an antifrictional roller 12, which lies under and bears against the foot-piece 8, so that as said lever-arm oscillates the lift-rod is moved up anddown, carrying the ring-rail section with it. Another rock-shaft, 13, is provided with a single-arm lift-lever 14:,rigidly connected therewith and provided at its end with an antifrictional roller 15, which works under the foot-piece of another lift-rod, which supports the adjoining ringrail section. Between the rock-shafts and 13 .is another rock-shaft, 16, to which is rigidly secured a double-arm lift-lever comprising oppositely-extending arms 17 and 18, each of which is provided at its extremity with an antifrictional roller 19, which works in connection with the foot-piece of another lift-rod, 3. i

Each of the rock-shafts 10 and 13 and 16 is provided with an upwardly-extending crankarm 20, and all of said crank arms are connected together for simultaneousmovement by a coupling-rod 21, which is pivotally at tached to each crank-arm, so that as one'crankarm is vibrated the other crank-arms are simultaneously vibrated, thereby giving an equal throw to each of the lift-levers 11, 14, 17, and 18, which are of equal length, the arms or levers 11 and 17 extending in one direction and the levers 14 and 18 extending in the reverse direction. In this way as the ringrail section 1 is raised the adjoining ring-rail section 2 is lowered, and vice versa.

22 designates a connecting-rod which is provided at one end with a clip or elbow 23, to which it is threaded, said clip or elbow being adjustable vertically in a slot 24 in one of the crank-arms 20, as shown in Fig. 1. To the opposite end of the connecting-rod 22 is ad justably attached by threading or otherwise a yoke 25, which is pivotally attached at 26 to the lower bifurcated end 27 of a cam-operated lever 28, which is fulcrumed at its upper end, as at 29, in a fork 30, provided with a shank 31, adjustable up and down in a sleeve 32, which is also provided with a shank 33, adjustable horizontally in asleeve 34 of a bracket 35, attached to and projecting from a part 36 of the machine-frame, as shown in Fig. 1. Between the branches of the fork 27 is journaled an antifrictional roller 37 which operates in contact with the cam 38, mounted on the shaft 39, which also carries a worm-gear 40, driven by a worm-shaft 41, provided with a driving-wheel 42. The wheel 42 is preferably provided with sprocket-teeth or their equivalent in order that it may derive its motion from a sprocket-driving chain.

From the foregoing description it will be understood that as the shaft 41 is rotated by the means described rotary motion will also be imparted to the shaft 39, causing the cam 38 to act on the lever-28, vibrating the latter and by means of the connecting-rod 22 imparting a vibratory movement to the crankarm 20, to which the connecting-rod is attached. As said crank-arm is coupled up with all the other crank-arms, which are of equal length, uniform rocking movement is imparted to all of the shafts 10, 13, and 16, and consequently to all of the lift-levers carried by said rocking shafts. In this way the lift-rods 3 are reciprocated vertically in their guides and the ring-rail sections are uniformly moved up and down simultaneously and'equally, one ring-rail section serving to counterbalance another.

In order that an operative engagement may be maintained between the cam 38 and the lever 28, one of the rock-shaftsfor instance, the rock-shaft 13is provided with a weighted arm 43, carrying a balance-weight 4A, which may be adjusted in and out on said arm. By means of the weight 44 the ring-rail sections may be said to be overbalanced to an extent sufficient to hold the lever 28 against the cam 38, thereby insuring the proper action of the mechanism by means of which motion is imparted to the ring-rail sections.

It will be apparent that the construction hereinabove described is susceptible of considerable modification in the form, proportion, and minor details, and I therefore reserve the right to make such changes as properly fall within the scope of the appended claims.
